[cleanup] Remove obsolete "one byte data hint" for strings. In the early days of Chrome when we used WebKit there was no support for ASCII strings on the C++ side, so we put a hint onto these two-byte strings that said "string only contains one byte data", such that internally in V8 when these were involved in string operations, we could instead create the *cheaper* one byte strings. Nowadays Blink properly supports one-byte string representations and this additional hint only comes with overhead, since we check it in quite a few places (i.e. on the hot path for string concatenation), plus we end up consuming more memory due to the additional string maps. Removing the hint also frees one bit in the InstanceType zoo for strings. This alone improves performance on the `bench-dom-serialize.js` test case by around **3%**.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

[torque] improve GC visitors Summary of changes: - GC visitors no longer rely on superclass visitors, but instead visit everything themselves. This enables generating better code. - Try to match simple body descriptors to reduce the amount of generated code. - Turn SizeFor(instance) into an AllocatedSize() method. - Remove the special handling of resizable object sizes from Torque and instead overwrite AllocatedSize in classes that need special handling in C++. - Split the visitor id lists depending on whether the class has pointer fields. - Turn Torque-generated body descriptors into an .inc file to simplify includes. - Fix generated size functions to properly align the size. - Generate GC visitors (and C++ class definitions) for all string classes and FixedArray, WeakFixedArray, and WeakArrayList. - Store generated instance types in Torque class types. This is only used to determine if a type has a single instance type in this CL.

[wasm-c-api] Cache CapiCallWrappers in the NativeModule We used to recompile WasmCapiCallWrappers whenever they were needed, but never garbage-collected them, which caused a memory leak when many short-lived instances of the same module were created.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

Reduce max instance type enum value. We collect instance type statistics in FatalProcessOutOfMemory into an array, which is allocated to the max instance type value. While we want to leave space to ensure new instance types do not affect constants in the API, we can be more frugal. We currently serialize 350 maps into the startup/context snapshot. Even if we assign a distinct instance type to each of these maps, we would still have more than enough to spare with this change.

Create Instance Type for Class Constructors Class Constructors are special, because they are callable but [[Call]] raises an exception. Instead of checking if a JS function is a class constructor for every JS function call, this CL adds a new instance type for class constructors. This way we can use a fast instance type range check for the common case, and only check for class constructors in the uncommon case were a class constructor is called and when we need to raise an exception.

Remove 'length' field from ScopeInfo This change relands the last part of https://crrev.com/c/2601880 . ScopeInfo has a vestigial 'length' field from when it used to be a FixedArray. This change removes that field, which saves some memory. More specifically: - Make ScopeInfo inherit from HeapObject, not FixedArrayBase which supplied the 'length' field. - Change FactoryBase::NewScopeInfo to allocate the updated object shape. It maintains the existing behavior of filling the newly-allocated object with undefined, even though that's not a valid ScopeInfo and further initialization is required. - Change a few length computations to use HeapObject::kHeaderSize rather than FixedArray::kHeaderSize. - Remove an unnecessary heap verifier function.

[wasm-c-api] Cache CapiCallWrappers in the NativeModule We used to recompile WasmCapiCallWrappers whenever they were needed, but never garbage-collected them, which caused a memory leak when many short-lived instances of the same module were created. This patch makes the wrappers cacheable and caches them, which avoids both repeated compilation effort and the unbounded memory growth. Drive-by cleanup: unify WasmCapiFunctionData with the other Wasm*FunctionData classes by making it inherit from WasmFunctionData.

Reland "[turbofan] extend type asserts to cover all JS types" This is a reland of 45227ffdb4319de48205a27cb5107342ac5a863e Differences: - Handle one more flags conflict in variants.py. - Disallow %VerifyType without --concurrent-recompilation. Original change's description: > [turbofan] extend type asserts to cover all JS types > > Extend type assertions to all types covering JavaScript values. > This is achieved by allocating type representations on the heap using > newly defined HeapObject subclasses. To allocate these in the compiler, > we disable concurrent compilation for the --assert-types flag for now. > > Fix two type errors that came up with the existing tests: > 1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of > OtherObject. > 2. OperationTyper::NumberToString(Type) can type the result as the > HeapConstant Factory::zero_string(). However, NumberToString does > not always produce this string. To avoid regressions, the CL keeps > the HeapConstant type and changes the runtime and builtin code to > always produce the canonical "0" string. > > A few tests were failing because they check for truncations to work > and prevent deoptimization. However, AssertType nodes destroy all > truncations (which is by design), so these tests are incompatible > and now disabled for the assert_types variant. > > Drive-by fix: a few minor Torque issues that came up. > > Change-Id: If03b7851f7e6803a2f69edead4fa91231998f764 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3234717 > Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> > Reviewed-by: Omer Katz <omerkatz@chromium.org> > Commit-Queue: Tobias Tebbi <tebbi@chromium.org> > Cr-Commit-Position: refs/heads/main@{#77565} Change-Id: I5b3c6745c6ad349ff8c2b199d9afdf0a9b5a7392 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3247035 Auto-Submit: Tobias Tebbi <tebbi@chromium.org> Commit-Queue: Nico Hartmann <nicohartmann@chromium.org> Reviewed-by: Omer Katz <omerkatz@chromium.org> Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> Cr-Commit-Position: refs/heads/main@{#77596}

Create Instance Type for Class Constructors Class Constructors are special, because they are callable but [[Call]] raises an exception. Instead of checking if a JS function is a class constructor for every JS function call, this CL adds a new instance type for class constructors. This way we can use a fast instance type range check for the common case, and only check for class constructors in the uncommon case were a class constructor is called and when we need to raise an exception.

Remove 'length' field from ScopeInfo This change relands the last part of https://crrev.com/c/2601880 . ScopeInfo has a vestigial 'length' field from when it used to be a FixedArray. This change removes that field, which saves some memory. More specifically: - Make ScopeInfo inherit from HeapObject, not FixedArrayBase which supplied the 'length' field. - Change FactoryBase::NewScopeInfo to allocate the updated object shape. It maintains the existing behavior of filling the newly-allocated object with undefined, even though that's not a valid ScopeInfo and further initialization is required. - Change a few length computations to use HeapObject::kHeaderSize rather than FixedArray::kHeaderSize. - Remove an unnecessary heap verifier function.

[snapshot] Keep fewer objects in the shared heap object cache Tip of tree puts both internalized and in-place-internalizable strings into the shared heap object cache. But only internalized strings need to go in there, since we can't have duplicates of those. It's fine to allocate in-place-internalizable strings in the shared heap each time a new Isolate is initialized, it'll be deduplicated if it's internalized eventually.

[wasm] [debug] Implement calling imported wasm functions The interpreter was not able to call imported wasm functions (hitting UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is signature-specific. It has JS linkage and receives the wasm code object to call and a buffer containing all arguments (similar to the interpreter entry). It loads all arguments from the buffer and calls the given code object. The c-wasm-entry code objects are cached per instance, such that we only create them once per signature. These wasm entry stubs will also allow us to call back to compiled code from the interpreter, which we might want to do to reduce the slowdown of executing wasm for debugging.

"STUB",
Inline Array.prototype.forEach in TurboFan This CL contains a few pieces: - A new mechanism to create "BuiltinContinuation" checkpoints in TurboFan graphs, which--when triggered--swizzle the values in the the FrameState to be parameters to a typically TF-generated builtin that resumes execution to finish the slow-case functionality. - Continuation builtins that have special handling in the deoptimizer and their own new frame type to ensure that the values they need to begin executing can be stashed away and restored immediately before the builtin is called via a trampoline that runs when the continuation builtin's frame execution resumes. - An implementation of Array.prototype.forEach in TurboFan that can be used to inline it. The inlined forEach implementation uses the checkpoints mechanism described above to deopt in the middle of the forEach in the cases that optimization invariants are violated. There is a slightly different continuation stub for each deopt point in the forEach implementation to ensure the correct side-effects, i.e. that the deopt of the builtin isn't programmatically observable.
